teraelectron

Teraelectron is a unit of electric charge, representing 10^12 (one trillion) electrons. In the International System of Units (SI), the elementary charge of a single electron is approximately 1.602 x 10^-19 coulombs. Therefore, a teraelectron is equivalent to 1.602 x 10^-7 coulombs. This unit is not commonly used in everyday contexts but can be relevant in fields such as particle physics, semiconductor technology, and materials science, where extremely large numbers of electrons are involved. For instance, in the context of semiconductor doping, a teraelectron might refer to the number of dopant atoms introduced into a material to alter its electrical properties. The term is derived from the prefix "tera-," which denotes a factor of 10^12, and "electron," the fundamental negatively charged particle.
